Thank you! I wasn’t using it correctly inside the component.
Out of interest, do you know what happens to the file once you upload it? Does it get stored in an online database? Does it get deleted at the end of the process run? Or will the file stay there until its deleted?
either the file is stored in a temp folder in the workflow directory (e.g./path/to/workflow/tmp/file_name). This the default behavior, and you can change it by unchecking the checkbox in the node config.
or it will be created in the temp directory of the system. Note that this can cause problems e.g. with file system access when running on KNIME Server.
The uploaded file will be deleted from the workflow when the workflow is discarded or reset.
KNIME does NOT collect any data in an online database, everything happens on your local machine or your instance/machine the KNIME Server is running on. We never collect your data nor do we have or want access to it!
